Uses: 
                 Diquat dibromide is a moderately toxic compound in EPA toxicity class II. It is a General Use Pesticide (GUP). Labels for products containing diquat dibromide must bear the Signal Word WARNING.
                 Diquat dibromide is a nonselective, quick-acting herbicide and plant growth regulator, causing injury only to the parts of the plant to which it is applied. Diquat dibromide is referred to as a desiccant because it causes a leaf or an entire plant to dry out quickly. It is used to desiccate potato vines and seed crops, to control flowering of sugarcane, and for industrial and aquatic weed control. It is not residual; that is, it does not leave any trace of herbicide on or in plants, soil, or water
